From The Lost Media Wiki
Jeffrey Cat: Claw and Order is an animated pilot created by Mark O'Hare (known for creating the comic strip Citizen Dog) for Cartoon Network, produced by Slappy Pictures. It was one of eight Cartoon Cartoon shorts exclusive to the Cartoon Cartoon Weekend Summerfest on August 23, 2002, where it lost to Lowbrow (later known as Megas XLR).
The pilot, titled "All Dogs Don't Go to Heaven", sees pet investigator Jeffrey Cat solving a case involving an innocent dog that has been accused of attacking a neighbor. It was the only Summerfest pilot that had not made its way online. However, on May 15th 2015, Dailymotion user "BrakCartman" uploaded the pilot. It can be viewed below.
